iavf_map_rings_to_vectors(9)

💅 iavf_map_rings_to_vectors(9) — the manual page, bestie edition 🎀

okay so this is the manual page for iavf_map_rings_to_vectors(9), and honestly? it's a whole vibe. it's a kernel API page, it's short, it's sweet, and it does exactly one thing. let's get into it 💖

---

✨ NAME ✨

iavf_map_rings_to_vectors — maps descriptor rings to vectors 🌀➡️📌

like... that's the whole job. it takes the descriptor rings and it maps them onto vectors. no cap.

---

📜 SYNOPSIS 📜

void iavf_map_rings_to_vectors (struct iavf_adapter *adapter );

that's it. that's the signature. void return, one argument, no drama 💅

---

🎀 ARGUMENTS 🎀

• adapter — the board private structure that you're gonna initialize, bestie 🫶 this is the thing that gets set up. it's the main character of this function, fr fr.

---

💖 DESCRIPTION 💖

okay so here's the tea ☕ this function's entire personality is mapping descriptor rings onto the queue-specific vectors that we were allotted way back through the MSI-X enabling code. that's the assignment and it ate ✨

ideally — and like, ideally ideally — we would have one whole entire vector per ring/queue. one ring, one vector, everyone living their best life, no sharing, no compromises, main character energy for every single queue 💅 but the universe said no, because sometimes you're on a constrained vector budget 😭 and in those cases we group the rings together as "efficiently" as we possibly can. note the quotes around "efficiently" — the original page put them there, and they are saying something 🙈

and here's the practical bit, so listen up: if you ever want to add new mapping configurations, this is the place to do it. this function is where that configuration lives. you would add new mapping configurations in here. periodt 🎯

and now, the icon list herself. every one of these is a (9) reference, all of them, and we are not skipping a single one because that would be rude 🫶

🌸 friendly reminder that this page comes to you from ./drivers/net/ethernet/intel/iavf, dated October 2026, and its whole title is iavf_map_rings_to_vectors(9). that's the copyright-adjacent bit, so we're saying it out loud like the good students we are 🎓

okay bye bestie, go map those rings 💅✨🦋
